| Abstract(in English) | Ultra-wideband (UWB) is a new wireless communications technology using very short pulses less than a few nano-seconds. Transmitting signal usually occupies several giga-hertz bandwidth. In UWB communications, timing jitter at puse generators causes the performance degradation. Narrowband interference (NBI) from conventional wireless communication entities is also a major degrading factor for error-rate performances in UWB systems. In this paper, we investigated impact of timing jitter and NBI in UWB system employing direct sequence spread spectrum (DS/SS) modulation. Gaussian monocycle pulse and modulated gaussian pulse is considered as the pulse waveforms. Simulation results show that root-mean-square (RMS) jitter should be less than a few percent of pulse width on order to maintain the ideal error-rate performance. If signal to interference ratio (SIR) becomes less than 20 dB, error rate performance is getting worse, especially modulated gaussian pulse is employed. |
